it depends if its a piss test because these are very easy to pass, i know this cause i was on supervised probation and they did drug tests and i passed every single one of them, all you gotta do is flush out your system, you can do this by drinking plenty of fluids be it water or kool-aid(i know alot of people have kool-aid) but see how this works is it flushes the trace amounts of whatevers in your pee out of your body so it doesnt pop up in your test....hope this helps you, and remember when someone tells you that it takes a month to get out of your systems means they havent smoked enough:stoned:
